Round-by-round scorecard

33

NotionObsidian
  1. Round 1PriceObsidian takes it

    Obsidian's full app is free without limits, even for work; Notion's free plan cripples multi-member workspaces and full AI needs the $20 Business plan.

  2. Round 2CollaborationNotion takes it

    Notion offers Google-Docs-style co-editing with unlimited guests; Obsidian is fundamentally single-player.

  3. Round 3Data ownership & offlineObsidian takes it

    Obsidian stores plain Markdown on your device and works fully offline; Notion's offline mode (2025) is partial, per-page, and databases cap at 50 rows.

  4. Round 4Databases & structureNotion takes it

    Notion's relational databases with synced views remain the benchmark; Obsidian's Bases (2025) narrows the gap but isn't relational.

  5. Round 5ExtensibilityObsidian takes it

    Obsidian's thousands of community plugins and open API outclass Notion's more closed platform.

  6. Round 6AINotion takes it

    Notion ships first-party agents, meeting notes and enterprise search; Obsidian has no first-party AI — only third-party plugins with your own API keys.

Why trust a comparison site?

Mostly, you shouldn't — the category is full of pay-to-win rankings and pricing tables that were last true in 2023. We do three things differently: every fact is verified against the vendor's own pricing page and stamped with its check date, verdicts are always split by use case instead of crowning a sponsor, and our methodology and revenue model are public.
